I have the SCT Handheld X3 powerflash. model 3000. I bought the truck about a year ago and never plugged the tuner in. The other day i plugged it in ror a pass on the "race" tune supposedly in there somewhere. The truck was profesionally tuned at a shop. It is currently "supposedly" on the "street" tune. When i plugged it in i Bailed after the first couple screens. I had other vehicles and tuners but they were pretty straight forward in selecting a tune setting. Any help is appreciated. Btw i believe the truck was tuned by RWTD if that helps.
